Resolve Pay vs Billtrust vs Melio

Choosing between B2B payment platforms gets complicated fast because these three products sit in different parts of the finance stack. One is built to help sellers offer net terms without tying up working capital. Another is centered on enterprise accounts receivable operations. The third is widely used for small-business bill payments and payment workflows. That means this is not just a feature comparison. It is a question of which platform aligns with the financial workflow you are trying to improve.

For suppliers, manufacturers, wholesalers, and distributors, the biggest issue is usually not invoice creation alone. It is the cash flow gap that opens when buyers expect terms but the seller still needs to fund inventory, payroll, and operations. That is where Resolve Pay stands apart. It combines net terms, buyer underwriting, receivables workflows, and payments in one platform built for B2B sellers. As digital payment adoption and workflow automation continue to reshape finance teams, with ongoing signals from the Federal Reserve, the Census Bureau, and the World Bank, platform choice increasingly affects both growth and cash conversion.

Key Takeaways

• Resolve Pay is built for B2B sellers: It helps merchants offer net terms, automate receivables, and improve cash flow without taking on the full burden of credit operations.
• The three platforms solve different problems: Resolve Pay is seller-side finance infrastructure, Billtrust is AR automation software, and Melio is primarily geared toward business payment workflows.
• Credit risk is a major dividing line: Resolve Pay underwrites buyers and supports non-recourse programs on approved invoices, which changes the economics of offering terms.
• Integration depth matters: Resolve Pay connects with ecommerce, ERP, and accounting systems so teams can embed terms and payments into existing workflows.
• Operational fit matters as much as feature fit: Businesses comparing these tools should start with whether they need financing, receivables automation, or bill pay orchestration.
• Resolve Pay brings multiple workflows together: Instead of stitching together separate credit, collections, and payment tools, sellers can manage more of the order-to-cash process in one place.

Quick Overview of Each Platform

Resolve Pay

Resolve Pay is a B2B payments and net terms platform built for sellers that want to offer payment terms while protecting cash flow. Its platform combines accounts receivable, buyer underwriting, invoicing, collections, and payment workflows in one system. According to Resolve Pay’s product pages, businesses can offer Net 30, 45, 60, or 90 terms, use a branded payment portal, and connect workflows across commerce and finance systems through its integrations.

The platform is especially relevant for merchants, manufacturers, wholesalers, and distributors that want to give buyers more purchasing flexibility without manually managing every step of the receivables cycle. Resolve Pay also supports business credit checks and positions itself as a modern factoring alternative for B2B sellers that want more control over customer experience and back-office workflows.

Billtrust

Billtrust is an accounts receivable platform focused on invoice-to-cash operations for finance teams. On its official site, Billtrust describes its offering as AI-powered AR automation spanning invoicing, payments, collections, credit, and cash application, with support for enterprise workflows and a broad integration ecosystem. It also states that it has more than 24 years of AR experience, processes about $1 trillion in transactions annually, and offers 40+ connectors across ERPs, banks, and financial institutions.

That makes Billtrust a recognizable option for organizations modernizing billing, payment acceptance, reconciliation, and collections across larger AR environments.

Melio

Melio is a business payments platform widely associated with accounts payable and payment execution for small businesses. On its official site, Melio emphasizes paying bills by ACH or card, vendor payment workflows, and two-way sync with QuickBooks and Xero. Melio also supports receiving payments through invoicing and online payment workflows, which makes it broader than a pure AP tool, but its core positioning remains centered on helping businesses pay vendors and manage outgoing payments.

What problem does each platform solve?

Resolve Pay focuses on the seller cash flow gap

When B2B sellers offer terms, they often create a tension between revenue growth and liquidity. Buyers want flexibility, but the seller still has to wait to collect. Resolve Pay is designed to solve that gap by combining net terms management, buyer approval workflows, and receivables automation into a single seller-side system.

This matters most for businesses that want to extend terms without turning their finance team into a manual credit and collections department. Resolve Pay’s own platform materials highlight automation across credit, invoicing, reconciliation, collections, and payment workflows, plus support for a branded buyer experience and multiple payment methods.

Billtrust focuses on enterprise AR efficiency

Billtrust is designed for teams that need to improve invoice delivery, payment collection, cash application, and order-to-cash visibility at scale. Its official platform overview places heavy emphasis on AI-powered AR automation, configurable workflows, and integration with finance systems used in larger organizations.

For companies that already have their financing model in place and want to improve AR operations, Billtrust fits that workflow well.

Melio focuses on business payment execution

Melio’s core use case is simpler and narrower. It helps businesses pay bills, send vendor payments, manage approvals, and sync those transactions with accounting software. It also supports invoicing and receiving payments, but its main value is operational convenience around outgoing payments and lightweight payment administration.

Feature comparison

How the platforms differ in practice

Resolve Pay brings financing and AR operations together

A lot of software in this category helps with one layer of the process. Resolve Pay is notable because it combines several layers that are often fragmented across separate vendors: B2B payments, buyer underwriting, receivables automation, collections, and embedded terms workflows.

For B2B sellers, that has two practical advantages:

• It supports offering terms in a way that is tied to actual buyer approval and payment operations
• It reduces the amount of stitching required across credit checks, invoicing, reminders, reconciliation, and payment acceptance

That is why Resolve Pay is often the better fit for merchants that need a growth tool, a risk workflow, and a receivables operating layer in one platform.

Billtrust is oriented toward mature AR teams

Billtrust’s strength is operational scale inside AR. Its platform is structured around billing, collections, cash application, and credit workflows for finance organizations that want to modernize their order-to-cash environment. Billtrust also highlights a large implementation base, annual transaction volume, and a wide connector network for enterprise ecosystems.

That can make it relevant for larger finance organizations that are primarily optimizing AR execution rather than changing how they extend terms.

Melio is oriented toward payment convenience

Melio is easiest to understand as a business payments workflow tool. Its official materials focus on paying bills, using ACH or card, syncing with accounting systems, and managing payment flows without heavy implementation work. It also supports invoice-based incoming payments, but the overall product positioning stays close to small-business payments and AP administration.

How Resolve Pay handles credit risk and collections

Credit decisions are part of the product

One of the most important differences in this comparison is that Resolve Pay is built around the reality that B2B sellers need a structured way to approve buyers before extending terms. Resolve Pay’s official product pages describe AI-driven credit decisions, underwriting, and workflows that help merchants offer terms without manually evaluating every account.

That is a very different starting point from software that begins with bill pay or general AR automation.

Collections are built into the workflow

Resolve Pay also describes collections and payment follow-up as part of the platform experience, combining AI agents and AR operations to reduce manual effort across the receivables cycle. That fits the needs of finance teams that want fewer disconnected tools and a more consistent process from approval through repayment.

For businesses comparing options, this is often where Resolve Pay becomes the more complete seller-side platform.

Implementation and integrations

Resolve Pay is built for commerce and finance connectivity

Integration depth matters because B2B payment terms touch order flows, accounting records, customer data, and payment reconciliation. Resolve Pay’s integration stack includes ERP, ecommerce, and accounting systems such as NetSuite, Sage Intacct, BigCommerce, Shopify, Magento, WooCommerce, and flexible API connections.

That makes it easier to embed terms and payment workflows where customers already transact, rather than forcing a separate system of record.

Additional Resolve Pay resources that are relevant here include AR automation, payment terms, B2B BNPL, and adding net terms online.

Billtrust leans into enterprise connectivity

Billtrust emphasizes connector breadth and enterprise integration, including ERP-related workflows and configurable pathways between invoicing, payments, and financial systems. That supports its fit within large AR environments.

Melio keeps setup lighter

Melio’s integration story is more straightforward and more closely tied to QuickBooks and Xero workflows for smaller teams. For businesses that mainly want to pay vendors and keep books synchronized, that simplicity can be attractive.

Who should choose Resolve Pay?

Resolve Pay is the strongest fit when your business is trying to do more than digitize invoices or pay bills. It is especially relevant when you want to grow B2B sales by offering terms while keeping cash flow and receivables operations under control.

Resolve Pay is a strong fit if you:

• Sell to other businesses and want to offer Net 30, 45, 60, or 90 terms
• Need buyer approval and credit management built into the workflow
• Want receivables automation alongside payment workflows
• Need a branded payment experience
• Want ERP, accounting, and ecommerce connectivity in one platform
• Are evaluating a more modern factoring alternative

For B2B sellers, the biggest advantage is that Resolve Pay is designed around the seller’s full order-to-cash reality, not just one isolated step in the process.

Why Resolve Pay stands out in this comparison

Billtrust and Melio each serve real use cases, but they sit in different operating lanes. Billtrust is primarily an AR automation platform. Melio is primarily a business payments workflow platform. Resolve Pay is the platform in this comparison that is purpose-built around helping B2B sellers offer terms, automate receivables, and manage payments in one connected system.

That makes Resolve Pay the most complete choice for businesses that want to:

• increase buyer purchasing flexibility
• improve cash conversion
• streamline collections and payment workflows
• support growth without expanding manual credit and AR work

If the core question is how to offer terms while staying operationally efficient, Resolve Pay is the clearest fit.
